Doctor Who

Season 2

New Earth

1. Russell T. Davies wrote this episode because Billie Piper requested that she would be given a comic role in the new season, as a counterpoint to the often very serious material she had tackled the year before.
2. In the beginning Billie Piper didn't know that she would be squirted with water in the lift. Russell T. Davies kept it in the final cut as he thought it was too funny to cut it. David Tennant wanted to watch this happen for the first time.
3. Adjoa Andoh who played Sister Jatt would later turn up in a semi-regular role as Martha Jones's Mother in Season Three.
4. The giant "BAD WOLF" graffiti written on a paved public area of Rose's estate (seen in Doctor Who: The Parting of the Ways (2005)) is still visible, though faded, at the start of the episode.
5. This episode is set twenty-three years after the events of the 2005 episode Doctor Who: The End of the World (2005), and thirty years prior to the events of the 2007 episode Doctor Who: Gridlock (2007).
6. Originally, Russell T. Davies intended the Face of Boe to impart his message upon the Doctor in this episode; when he discovered that a third series was definitely to occur, Davies quickly decided to delay Boe's message for a year. This is one of several plot and thematic details that Davies chose at a rather late stage of development to move from series two to three (including whole episodes, such as the 2006 Christmas special, Doctor Who: The Runaway Bride (2006)).
7. The Converse Chuck Taylor All Star trainers that the Tenth Doctor wears are actually David Tennant's personal shoes.
8. This episode marks the first appearance of a running joke about the Tenth Doctor's love of the "little shops" found in hospitals and museums.
9. Billie Piper's boyfriend visited the set and accidentally damaged The Face of Boe prop.
10. Cassandra's 'stretched skin' appearances were kept to a minimum because these scenes were gruelling to computer-animate.
11. All of Billie Piper and David Tennant's dialogue when they first arrive on New Earth had to be re-dubbed in the studio, as the windy conditions on the location shoot made it difficult for the microphones to pick their lines up.
12. The TARDIS is in a different location at the beginning compared to the final scene in The Christmas Invasion, implying there may well have been other adventures between these two stories (i.e. Doctor Who: Attack of the Graske (2005)) but some references to the Doctor being a new Doctor do imply that only a little time has passed since Christmas.
13. This episode marks the first use of the Tenth Doctor's recurring phrase "I'm sorry, I'm so sorry" in the series.
14. The first story of the revived series to show an alien planet on screen.
15. The shoot was hampered by high winds and rain, forcing the abandonment of the final scene to be recorded. Planned to bridge the final hospital sequence and the material at the party, this would have seen the Doctor reminding Cassandra (now in Chip's dying body) that he still hasn't forgiven her for the deaths she caused in "The End of the World." The uncooperative weather was not the only misfortune to befall the day's recording: it was belatedly discovered that a camera had malfunctioned during the shoot, resulting in the loss of several close-ups.
16. This is the first Doctor Who episode to have an accompanying Tardisode. These short prelude scenes were made available online and via cellphone a week prior to the broadcast. In the case of New Earth the Tardisode consisted of a faux commercial advertising the Sisters of Plenitude's services.
17. Michael Fitzgerald's prosthetics costume was so large that it had to have his own cooling system to save him from passing out in the heat.
18. Zoë Wanamaker filmed her cameo in one day.
19. Another reference to a planet called "New Earth" in Doctor Who occurred in Doctor Who: Invasion of the Dinosaurs: Part Four (1974), when Sarah was taken aboard a spaceship to be brainwashed and taken to a new world. Other "New Earth" references have also appeared in non-canonical Doctor Who media, such as books and comics.
20. Copies of the DVD from the complete Series 2 set distributed to Netflix customers contained an error: at the 32-minute mark, the playback switched abruptly to a scene from The Texas Chainsaw Massacre: The Beginning (2006). Netflix has pulled the disc from their inventory while they work out the issue with the BBC; this only seems to have affected Netflix copies.
21. The words "bitch" and "arse" are implied, although not actually said. In both cases, the character (Cassandra and Rose, respectively) is cut off in her dialogue and the words are implied by the next word in the script. Cassandra, when talking of Rose, calls her "that little..." and then the scene cuts to Rose whose first words are "a bit rich". Later, Rose tells Cassandra she is "talking out of [her]..." and Cassandra interrupts, "Ask not!"
22. When the wall drops, the sound made is recycled from the movement of the Daleks.
23. Working titles for this story included Body Swap and The Sunshine Camp.
24. The location for the pods containing the human specimens was a disused paper mill previously used as the base of the Nestene Consciousness in Doctor Who: Rose (2005).
25. This episode was watched by 8.616 million viewers on its original transmission.
26. The Sisters of Plenitude were originally called The Sisters of Patience.
27. Cassandra's servant was envisioned as a dwarf named Zaggit, but as the character's importance grew during the scripting process, he developed into Chip.
28. Although it is widely stated that Rose has met the Face of Boe twice, the only times she was in his presence in this episode was during the periods where Cassandra was possessing her body, and he teleports away before Cassandra takes over Chip.
29. At one point, stock footage from Doctor Who: Rose (2005) is used.
30. This episode takes place in 2007 and 5000000023.
31. The episode was originally set on the planet Coffra.
32. The first season premiere to not take place in the present day.
33. Like the animated series Futurama (1999), this episode also features a rebuilt, futuristic city called New New York. In Futurama, however, New New York is built on the remains of "old" New York on Earth, with the events of the series taking place in the year 3000.
34. As the Doctor is discussing shops with the nursing cat sister, Morse code can be heard getting louder from approximately 6:50 through 7:06, which may be repeating SOS (di-di-dit-dah-dah-dah-di-di-dit).
35. Russell T. Davies explains during the audio commentary that in the original script, the Face of Boe was going to die in this episode and the only way for the Doctor to cure all the diseased was to kill them all. But then he read Steven Moffat's introduction segment in The Season One Shooting Scripts book, in which Moffat good naturedly mocked Davies, saying he 'creates interesting characters and then melts them'. This made Davies decide to have them all survive instead.
36. According to David Tennant on the audio commentary, Billie Piper wore a wonder bra and a slightly different shade of lipstick in the scenes where Cassandra was in Rose's body. He also mentioned that Billie kept on wearing the wonder bra for a bit longer after Cassandra was no longer possessing Rose.
37. The scene showing Rose kissing the Doctor was featured in one of the trailers and raised a stir in fan circles, despite the "kiss" shared by the Ninth Doctor and Rose in Doctor Who: The Parting of the Ways (2005). Ultimately, we learn it's actually Cassandra doing the kissing while possessing Rose. Rose and the Doctor never do kiss on screen in that fashion, though Rose will eventually kiss the Meta-Crisis Tenth Doctor in Doctor Who: Journey's End (2008).
38. Noel Clarke only has one line in this story.
39. Because production fell behind schedule, several scenes were dropped. Many of these concerned the Duke of Manhattan and Frau Clovis. Originally, they first appeared in the hospital foyer when the Doctor initially arrives; as scripted, the Doctor immediately earns the Sisters of Plenitude's disfavour when he saves the Duke's life. Later, Clovis mutinies when the Duke refuses to help defend the hospital against the Intensive Care patients.
40. When Cassandra takes over the Doctor's body she references to some parts that have been "hardly used", a reference to the perceived asexual nature of the Doctor. This may also refer to the fact that this is a new (regenerated) body, and that he hasn't really had a chance to "use" most of the parts very much at this point.
41. Spoilers for later episodes: Rose's fate in Doctor Who: Doomsday (2006) is foreshadowed when on top of the elevator The Doctor tells Cassandra (in Rose's body) to hold on to the lever "with everything you've got".

Tooth and Claw

1. The Doctor, as "James McCrimmon," claims to have studied at the University of Edinburgh under Dr. Bell. Dr. Joseph Bell was a lecturer and expert in observational deduction. He served as a mentor of Arthur Conan Doyle, who used Bell as a model for Sherlock Holmes.
2. When the Doctor poses as a Scottish physician, David Tennant is actually speaking with his own accent, the first and only time he was able to do that during his time in the role.
3. Initially, the Doctor and Rose were both supposed to fake Scottish accents, and then forget to use them when the action started. Billie Piper's terrible Scottish accent put an end to that.
4. At one point during filming, Billie Piper's hair caught fire.
5. The Doctor passes himself off as Doctor James McCrimmon from the township of Balamory. Jamie McCrimmon was a companion of the second Doctor (Patrick Troughton), and the longest serving companion in terms of episodes (he appeared in 117 episodes). Sarah Jane Smith was the longest companion in terms of period of time, appearing in 3.5 seasons. Balamory is a fictional Scottish village where the popular children's television series Balamory (2002) is set.
6. Michelle Duncan and Jamie Sives were unable to attend the readthrough for this story, and their parts were read by David Tennant's parents, who happened to be visiting the Doctor Who set at the time. Tennant told reporters at the series' press launch, "Because it's set in Scotland they were delighted to be asked to read in. My Mum played Lady Isobel and my Dad played Captain Reynolds, and they were in seventh heaven. And they were genuinely cheesed off when they didn't get asked to play the parts for real! I was like 'chill-out Mum and Dad, back in your box!'"
7. At one point the Queen compares Sir Robert, played by Derek Riddell, to Sir Walter Raleigh, whom Riddell had recently played in The Virgin Queen (2006).
8. This episode introduces a recurring joke in which the Doctor, aghast at his companions' awful attempts at adopting local accents, quietly hushes them with a "Don't do that." Martha Jones gets the same treatment in Doctor Who: The Shakespeare Code (2007) and Doctor Who: The Infinite Quest (2007), while Donna Noble is on the receiving end in Doctor Who: The Unicorn and the Wasp (2008) and Doctor Who: Midnight (2008), although the latter example is not humorous.
9. It was Phil Collinson who suggested having the Koh-i-Noor - the great diamond brought to Queen Victoria from India by Lord Dalhousie in 1851 - form an integral part of the plot.
10. When Father Angelo is chanting in Latin he is saying:"Lupus magnus est, lupus fortis est, lupus Deus est."- which translates as:"The wolf is great, the wolf is strong, the wolf is God.".
11. Pauline Collins, who played Queen Victoria, had previously appeared on Doctor Who (1963)'s 1967 story arc "The Faceless Ones".
12. Pauline Collins is the first female Oscar-nominated performer to appear in the series.
13. Russell T. Davies developed a storyline set at Buckingham Palace involving an alien insect getting in Queen Victoria's eye. This was not what the production team wanted and the storyline was rejected.
14. The werewolf in this story is computer-generated. Pauline Collins stated in a BBC press release that there were two performance artists who demonstrated the movements that the werewolf would do and talked about the problems of overacting in a situation where one was simply reacting to a green screen.
15. Queen Victoria was not a hemophiliac, although she was a carrier, as were several of her daughters. One of her sons, Prince Leopold, was a hemophiliac and died from bleeding on the brain after a fall. Because of the way the genetic disorder works, the victims are almost always male, the carriers female.
16. According to the accompanying episode commentary, Tom Smith, who played the Host, attended drama school with David Tennant.
17. This episode was watched by 9.240 million viewers on its original transmission.
18. Russell T. Davies initially planned for the Doctor to give his name to Queen Victoria as a Scottish equivalent of his usual "John Smith" alias. He had difficulty finding something suitable, however, and quickly came up with idea of using the pseudonym James Robert McCrimmon.
19. This episode takes place in 1879.
20. A deleted scene was included on the boxset DVD, where the Doctor and Rose, after being knighted, run off towards the TARDIS.
21. The warrior monks were inspired by Crouching Tiger, Hidden Dragon (2000).
22. Annette Crosbie was first offered the main guest lead of Queen Victoria. She had previously played the character in Edward the King (1975).
23. David Tennant's character also interacts with Queen Victoria in the animated film The Pirates! Band of Misfits (2012).
24. The working title for this episode was Queen Victoria.
25. In dialogue subsequently deleted in editing, the steward was called Jacob.
26. Jenna Coleman, who portrayed companion Clara Oswald, would go on to play a young Queen Victoria in Victoria (2016).
27. This is the second time The Doctor's female companion got called for being naked for wearing too little clothing in the late 19th century. The first time was in Doctor Who: Ghost Light: Part One (1989).
28. In Doctor Who: The Knight of Jaffa (1965) (The Crusade), William Hartnell's Doctor wistfully comments "I almost wish I was knighted too" after seeing Ian Chesterton being dubbed Sir Ian by Richard Lionheart himself. To that Vicky replies: 'That'll be the day!'; and so indeed, his knighthood from Queen Victoria marks the day.
29. At one point, Russell T. Davies contemplated surprising the viewers by having the werewolf kill Queen Victoria in 1879. This would the Point of Divergence for the alternate history introduced in Doctor Who: Rise of the Cybermen (2006) later in the season. However, Davies became concerned that this ongoing storyline would be too difficult for casual viewers to follow, and decided to drop the idea.
30. Torchwood Reference: The estate on which Sir Robert lives is called Torchwood. After the events take place, Queen Victoria vows that to honor the acts of Sir Robert, she would found an institute dedicated to finding such strange events. She would name it The Torchwood Institute.
31. In the narrative behind Queen Victoria deciding to form the Torchwood Institute and declaring that The Torchwood Institute will deal with The Doctor if he ever returns. Queen Victoria believed that The Doctor was evil and she made it her declaration that the Torchwood Institute will fight The Doctor and other extra terrestrial menaces that threaten the United Kingdom and that the Torchwood Institute will be ready to deal with him if he ever returns. This sets up the Torchwood Institute arc in Series 2 and the spin-off series Torchwood (2006) which Captain Jack Harkness takes over the organization in The Doctor's honor and The Torchwood Institute no longer fights The Doctor.
32. Script editor Simon Winstone has said that mistletoe is not indigenous to Scotland, and therefore its heavy presence in this story is supposed to further alert knowledgeable viewers that Sir Robert's father had deliberately imported it as a defence against the wolf.
33. The Doctor jokes about taking Rose to meet the Elephant Man. Merrick was famously played in the film The Elephant Man (1980) by John Hurt, who would later play the War Doctor in this series.
34. Rose tries to get Queen Victoria to say, "We are not amused"; however, she ends up saying, "I am not amused". The Doctor and Rose are still delighted, however.

School Reunion

1. To make Sarah Jane and Rose continue laughing the make-up artist painted a moustache on David Tennant without them knowing until he came on set. (Which is why at one point you see Rose point at him while laughing.)
2. Elisabeth Sladen warned the crew about the difficulties with working with the K-9 prop, which had a reputation for breaking down. Despite several years of improvement in technology, Sladen's warnings were proved correct.
3. The Doctor's reaction when talking to Sarah Jane for the first time required little acting for David Tennant. Having already been a fan of Elisabeth Sladen since childhood, he was genuinely thrilled to work with her.
4. Anthony Head's line "Forget the shooty dog thing", is a form of Buffy Speak, the type of slang used on Buffy the Vampire Slayer (1997), which Head starred in.
5. Sarah's last line to K9 is "We've got work to do." This was also the last line of the original series run, at the conclusion of the Seventh Doctor story Survival.
6. The K9 prop used at the end of the episode is one of the original props from the 1970s.
7. The original script had Sarah Jane Smith be a recovering alcoholic, but Elisabeth Sladen suggested the lines be removed.
8. Filming at Da Vinci's Coffee Shop in Newport for scenes in the cafe was hampered by the presence of several unruly drunks.
9. Sarah Jane wasn't given her K9 in a standard adventure. She was given K9 in the one and only episode of its first spin-off, K-9 and Company: A Girl's Best Friend (1981).
10. Several moments were trimmed or excised in editing. Banter between Kenny, Melissa, Luke and Faisal prior to the Doctor entering the classroom in the teaser - which would have fleshed out the children's characters - was cut. Later in the same scene, the Doctor's questions to Milo would have actually made him collapse, prompting the Doctor to bring him to the school nurse (another Krillitane); this was still alluded to in Wagner's dialogue with Melissa. The Krillitanes eating the hermetically-sealed rats was removed, and instead replaced by a voiceover explanation by the Doctor. Another voiceover was used to truncate the scene in which Kenny deduces that the fire alarm will disorientate the Krillitanes.
11. The aliens were initially Krillians, but when it was discovered that the name was already trademarked, they became Krillitanes.
12. The chips subplot was inspired by the recent controversy over school menus incited by Jamie's School Dinners (2005).
13. The appearance of K9 Mark IV at the story's end was also omitted from early drafts. Bob Baker, the co-creator of K9, requested it be put in. However, Russell T. Davies had already asked Toby Whithouse to incorporate such a scene into his script.
14. Anthony Head was screen tested for the Eighth Doctor in Doctor Who (1996).
15. The Tenth Doctor tells Sarah Jane he has had "half a dozen" regenerations since they last met. At the time the episode was aired, this seemed to be counting forward from when Sarah Jane was a regular character as the companion of the Fourth Doctor (Tom Baker), which ignores that Sarah Jane appeared in the special 'The Five Doctors' where she met The Doctor in his fifth incarnation (Peter Davison). This discrepancy was later resolved with the release of the "Day of the Doctor" 50th anniversary special, which suggests that the War Doctor (John Hurt) was the 6th regeneration he was referring to.
16. K9's eye grill was initially filmed flashing in sync with his lines, not unlike the Daleks, until Phil Collinson saw the footage and nixed the practice (which was inconsistent with the robot dog's past appearances).
17. The Krillitanes' physical appearance changed greatly during the episode's development - originally they were all winged but otherwise human.
18. Although never indicated on-screen, the novelisation of The Sarah Jane Adventures: Invasion of the Bane (2007) revealed that the Doctor left Sarah Jane a sonic lipstick and other items in a secret compartment within K9. On-screen, the sonic lipstick debuts in the Invasion of the Bane episode, but no explanation is offered as to where it came from. It appeared for the first time on Doctor Who (2005) during Doctor Who: Journey's End (2008).
19. The headmaster was called Hector Finch until it was learned that there was a real teacher by that name; he was rechristened Lucas Finch.
20. This episode was watched by 8.308 million viewers on its original transmission.
21. The confrontation between the Doctor and Finch was originally scripted to happen in the school gymnasium but was moved to the pool, which James Hawes felt served as a more dynamic setting.
22. The original storyline submission for the episode was entitled Black Ops and it involved the Doctor meeting Sarah while investigating events at an army base neighboring an isolated village.
23. Sara Jane mentions meeting the Loch Ness monster. This happened in the Fourth Doctor serial Terror of the Zygons, which is also the serial that introduced the Zygons.
24. Anthony Head has not only appeared in two of the BBC's animated adventures - Doctor Who: Death Comes to Time: Death Comes to Time (2002) and Doctor Who: The Infinite Quest (2007). He also narrated Doctor Who Confidential (2005).
25. Phil Collinson got to voice K9 as some scenes were recorded, including the one set in the chip shop. (Only John Leeson's voice was heard in the finished production, however.) According to Julie Gardner, it was a moment of supreme joy for the producer.
26. K9 has been called a tin dog twice before, by the Time Lord Drax in "The Armageddon Factor" and Lady Adrasta in "The Creature from the Pit".
27. Mickey originally didn't appear in the episode.
28. This episode takes place in 2007.
29. Filming at Duffryn High School in Newport for the scene in which Mickey crashes the car into the front of the school was briefly delayed due to an asbestos scare.
30. The TARDIS was originally intended to be hidden in a supply closet. This plan eventually came to fruition some time later, during Doctor Who: Into the Dalek (2014)
31. Two different Welsh high schools were used for filming: Fitzalan High School in Leckwith and Duffryn High School in Newport.
32. A working title for this episode was Old Friends.
33. Sarah Jane has a Volkswagen car in this episode. By The Sarah Jane Adventures (2007), she has switched to a Nissan Figaro.
34. Phil Collinson took a week's vacation during the filming of this episode, forcing Julie Gardner to take over his duties for a week, something she claimed to have adored. She would later become the effective producer on "The End of Time", when credited producer Tracie Simpson had to break away from the Russell T. Davies production unit to work with Matt Smith and the Steven Moffat unit.
35. Sarah Jane says 'Home' and 'We've got work to do', mirroring the Seventh Doctor and Ace's conversation in the closing moments of Doctor Who: Survival: Part Three (1989). Although it may have simply been a coincidence, as Sarah is referring to 13 Bannerman Road, whereas Ace was referring to the TARDIS.
36. Upon realizing that the Doctor (Who is in his tenth incarnation) is the Doctor, he says to Sarah that he's regenerated half a dozen times since they last met. Whilst they last appeared together in Doctor Who: The Five Doctors (1983), in which the Doctor was in his fifth incarnation, Sarah's memory was likely erased when she returned home, but the Doctor's wasn't. At the time, this was an error as this line would suggest that the Doctor was in his 11th incarnation; however, this is in fact correct, as whilst the concept hadn't been thought of yet, he actually refers to the War Doctor referencing his incarnation. This is of course pure coincidence.

The Girl in the Fireplace

1. Sophia Myles was David Tennant's girlfriend at the time.
2. When the Doctor returns to Mme de Pompadour's room for the final time, the wall behind the fireplace has been painted blue with paler rectangles that resemble the TARDIS and its outer panels.
3. Steven Moffat was inspired by Audrey Niffenegger's novel "The Time-Traveler's Wife". He would go on to write the screenplay for the TV series adaptation of the novel in 2022.
4. Steven Moffat was dismayed to discover that the key exchange between Rose and Reinette in which they discuss the Doctor and the monsters had largely been trimmed down to just a few lines. He subsequently convinced Euros Lyn to reinsert the remainder of the dialogue.
5. This was planned as the second episode of the 2006 series, however when Russell T. Davies realised how experimental it had become in Steven Moffat's hands, he decided to move it to fourth in the running order between Doctor Who: School Reunion (2006) and Doctor Who: Rise of the Cybermen (2006).
6. The clockwork robots originally wore wigs which completely hid their faces in shadow. Phil Collinson was concerned that this would limit camera angles too severely and risked appearing comical, so the creatures were given carnival masks to wear instead.
7. In an interview with The Independent, Russell T. Davies said the episode is "practically a love story for the Doctor ... It's very understated, very beautifully done, but it's nonetheless a Time Lord falling in love and Rose's reaction to him falling in love with someone else."
8. The actual clockwork apparatus was a working prop, designed by Neill Gorton of Millennium Effects and constructed by Richard Darwin and Gustav Hoegen.
9. "The Girl in the Fireplace" won the 2007 Hugo Award for Best Dramatic Presentation, Short Form.
10. The Spaceship is designed in the shape of a key.
11. The working titles for this episode were 'Madame de Pompadour', 'Every Tick of My Heart' and 'Reinette and the Lonely Angel'.
12. For the dialogue between the Doctor and the seven year-old Reinette, Steven Moffat drew upon The Virgin New Adventures novel Love And War by Paul Cornell. This was the original source of the Doctor's claim that he is what monsters have nightmares about.
13. The robots driven by intricate clockwork and mechanical gears are based on self-operating machines called "automatons" which were present in 17th century Europe.
14. Mickey mentions to Rose about the Egyptian Queen Cleopatra, whom The Doctor had a relationship with in an earlier incarnation. Later, in Doctor Who: The Pandorica Opens (2010), River Song pretends to be Cleopatra. Both episodes were written by Steven Moffat.
15. Sophia Myles's gold and jewel encrusted gown in the final ballroom scene was previously worn by Helen Mirren in The Madness of King George (1994) and Jodhi May in Aristocrats (1999) (during the scene at the court of George III).
16. In a deleted scene, the Doctor met the cruel owner of the horse (Phylip Harries) that gets trapped on the Spaceship; he is trying to find the horse and threatens to hurt it when he finds it.
17. In the original script, it was that the "mind meld" with the Doctor is what actually attracts the clockwork robots to Reinette. Rose then offers Madame de Pompadour a gem which could erase all signs of contact with the Doctor from her mind, but she refuses because she does not want to forget him.
18. This episode takes place in the 51st Century, 1721, the 1730s, the 1740s, 1753, 1758 and 1764.
19. The weather was appalling for a lot of the day filming, and due to the very intricate nature of the costumes, the cast were not allowed out of their trailers or the set before a crew member ensured they had umbrellas brought to them.
20. The script originally contained out-of-order meetings between the Doctor and Reinette in which she recalls seeing him at her convent school, which he later visits.
21. Various members of cast found their costumes tight and would eat lunch standing up to avoid costume damage such as lost buttons.
22. The episode's script was nominated for the 2006 Nebula Award.
23. This is Mickey's first trip in the TARDIS as a companion. His name does not appear in the opening credits; the first triple opening credit would not occur until John Barrowman returned temporarily in Doctor Who: Utopia (2007) the next season; it's not until Doctor Who: A Christmas Carol (2010) in 2010 that an ongoing "third companion" receives a credit in the opening.
24. Russell T. Davies came up with the episode while doing research for Casanova (2005).
25. Two horses were used in the episode; one was used for the scenes in close quarters on the spaceship, and another for jumps.
26. This episode was watched by 7.900 million viewers on its original transmission.
27. After the Doctor comes back from the ball, he sings "I Could Have Danced All Night", which is from the musical "My Fair Lady".
28. Various VIP people from the BBC visited the set for this episode.
29. Throughout this episode, Mickey wears a T-shirt which has a picture of the Nintendo Entertainment System controller over the caption, "Know Your Roots". This particular T-shirt, a limited edition, could be obtained either by subscribing to the British Nintendo Official Magazine, or by being purchased at selected GameStation outlets. In Doctor Who Magazine #367 Noel Clarke admitted to being a Nintendo fan and to being the owner of a Nintendo DS console. He also comments upon the T-shirt in the commentary which accompanies the episode on the BBC Website. Appropriately, Mickey is involved in a video game-related adventure in the spin-off novel "Winner Takes All". Mickey also mentions playing a Playstation in Doctor Who: The Age of Steel (2006).
30. When reading each other's minds, Reinette says 'Doctor who? More than just a secret isn't it'. Steven Moffat played out this theme over the Matt Smith era.
31. Sophia Myles stated in an interview on Doctor Who Confidential (2005) that she did not have to audition for the role of Madame de Pompadour, she was offered it.
32. Jessica Atkins' only acting role.
33. The Doctor says "Always take a banana to a party, Rose. Bananas are good." This isn't the first time the Doctor has expressed his preference for the banana. The Sixth Doctor carried a banana in his pocket which he then gave to Peri in Doctor Who: The Two Doctors: Part One (1985)/Doctor Who: The Two Doctors: Part Two (1985)/Doctor Who: The Two Doctors: Part Three (1985). The Ninth Doctor discussed his preference for the fruit in Doctor Who: The Doctor Dances (2005) and then switched out Jack's sonic blaster with one.
34. It received an Appreciation Index of 84, considered "excellent".
35. Arthur, the horse, was not allowed to set foot in the ballroom in the climactic scene. The various elements of the Doctor riding Arthur through the mirror (the horse, the mirror breaking and the reactions of the extras in the ballroom) all had to be filmed at separate times and then composited together. David Tennant's head was superimposed upon that of the stunt rider in post-production. Initially, the programme's staff considered the use of special effects but realised this would be very expensive and rejected the idea.
36. Reinette is the first non-companion character to kiss the Doctor on-screen.
37. Take a look at the cup the Doctor is holding in the scene where Rose and Mickey are tied up. That is not the traditional wine glass, but one that is based, according to an urban legend, on the shape of the breast of Madame De Pompadour, the lady this story is about.
38. The horse "Arthur" also appears in the 50th anniversary special Doctor Who: The Day of the Doctor (2013) also written by Steven Moffat.
39. Because the horse was not allowed in the ballroom, Steven Moffat was asked to rewrite the story's climax, and came up with two alternatives: one in which the Doctor is thrown from the horse's back through the mirror (which was felt to be too humorous) and another where the Doctor simply smashes through the glass himself (while the horse is described in dialogue as having retreated to the TARDIS, where it proceeded to void its bowels). After episode writer Steven Moffat threw, in his own words, "the biggest queeny strop yet done on Doctor Who," the effects team did it anyway.
40. Although Reinette dies before she is able to accept the Doctor's offer of travelling in the TARDIS, she does briefly experience time travel when she steps through one of the holes in time and ends up aboard the vessel bearing her name millennia later.
41. An alternate ending would had seen Reinette leave with The Doctor, Rose and Mickey aboard the TARDIS.
42. Star Trek: The City on the Edge of Forever (1967) is speculated to be an influence behind this story. Both The Doctor and Captain Kirk travel back through time to Earth in the past and falls in love with beautiful and important women in those time periods and both stories end with the women's deaths which The Doctor and Captain Kirk regret.
43. While visually it was toned down due to fears of being too gruesome, Doctor Who: Frontios: Part One (1984)/Doctor Who: Frontios: Part Two (1984)/Doctor Who: Frontios: Part Three (1984)/Doctor Who: Frontios: Part Four (1984) also dealt with aliens capturing humans to embed them into technology, specifically to be the "driver".

Rise of the Cybermen

1. Roger Lloyd Pack broke his leg just days before filming began on the episode, requiring the scripts being rewritten to place John Lumic in a wheelchair.
2. Roger Lloyd Pack and David Tennant previously appeared as father Barty Crouch and son Barty Crouch Jr. (respectively) in Harry Potter and the Goblet of Fire (2005). In that story, Lloyd-Pack was on the side of the heroes and Tennant was a villain.
3. According to Russell T. Davies, the fact that Jackie has her 40th birthday was a deliberate, if obscure, reference to the fact that Rise of the Cybermen aired in the 40th anniversary year of Doctor Who: The Tenth Planet: Episode 1 (1966).
4. Torchwood References: The newscast on Rose's phone references a study released by "the Torchwood Institute" immediately after the story on Lumic's return; Pete Tyler asks a guest "How're things going at Torchwood?"
5. Rise of the Cybermen and Doctor Who: The Age of Steel (2006) were inspired by Spare Parts, a story featuring the fifth Doctor discovering the origins of the Cybermen, by Marc Platt, produced by Big Finish Productions. Marc Platt receives a 'With Thanks' on the end credits.
6. "Rise of the Cybermen" was broadcast 40 years after the Cybermen made their first ever appearance in Doctor Who: The Tenth Planet: Episode 1 (1966) which was first broadcast on 8 October 1966. It was the beginning William Hartnell's final story as the original Doctor.
7. Roger Lloyd Pack based his performance as John Lumic on the United States Defense Secretary Donald Rumsfeld. He said, "I thought, 'Who is a power-hungry mad person who believes he is completely right and has a lot of control?' Donald Rumsfeld came to mind. He's as bad a man as I see around now."
8. The original setting was a dying Earth whose inhabitants regularly augmented their organs in "Body Shops" run by Cybus Industries. Russell T. Davies found this scenario less than credible, however, and also felt that the original inspiration for the Cybermen - which drew on mid-Sixties paranoia about body part replacement - was outdated.
9. Rise of the Cybermen and Doctor Who: The Age of Steel (2006), which saw the long-awaited return of the Cybermen, whom last appeared in in 1988, was broadcast 40 years after the Cybermen made their debut Doctor Who: The Tenth Planet: Episode 1 (1966). In The Tenth Planet, The Cybermen were once a race of humanoids that came from Earth's long-lost twin planet Mondas that were converted into Cybermen. In this version, The 10th Doctor, Rose and Mickey encountered the Cybermen in a alternate time-line, which The Cybermen did not come from another planet, but were created by a crippled scientist John Lumic, whom converted people into the Cybermen.
10. The original script contained more Preachers including a hard-bitten woman named Esme, who survived to the audition stage. One of the actresses who read for the part was Freema Agyeman, later cast as companion Martha Jones.
11. On a somewhat trivial note, this story reintroduces the Cybermen's iconic teardrop motif after a 31 year absence. This aspect of their design had last appeared in 1975's Doctor Who: Revenge of the Cybermen: Part Four (1975), having been present on their faces since 1968's Doctor Who: The Wheel in Space: Episode 6 (1968); all Cyberman appearances from 1982's Doctor Who: Earthshock: Part One (1982) to 1988's Doctor Who: Silver Nemesis: Part Three (1988) featured the Cybermen sporting their original circular eye-holes. The teardrop motif would reappear in all future Cyberman designs as of Series 8.
12. This episode was watched by 9.221 million viewers on its original transmission.
13. Mickey sports a large tattoo on his right biceps; according to actor Noel Clarke's commentary, the tattoo was make-up applied for the episode.
14. This is the first TV story to not feature any extraterrestrial elements other than The Doctor and the TARDIS since Doctor Who: Black Orchid: Part One (1982)/Doctor Who: Black Orchid: Part Two (1982).
15. Tom McRae envisioned the parallel counterparts of Mickey, Jackie and Pete as being much more at odds with their usual portrayals, but this was scaled back by Russell T. Davies.
16. According to Graeme Harper on the episode commentary, the pre-credits sequence was written by Russell T. Davies as he was not satisfied with the original opening.
17. Originally, the time rotor of the TARDIS was shattered at the start of the story, an effect ruled out on the grounds of cost.
18. The characters of Dr. Kendrick and The Newsreader were added and filmed after production had finished.
19. John Lumic was originally named Jacob. He also had a son, who was essentially replaced by Mr. Crane.
20. The working title for this episode was Parallel World.
21. Colin Spaull played the role of Lilt in Doctor Who: Revelation of the Daleks: Part One (1985)/Doctor Who: Revelation of the Daleks: Part Two (1985), which was also directed by Graeme Harper. Spaull is the sixth actor to appear in both the original series and the revival.
22. Graeme Harper suggested Don Warrington for the role of President.
23. The Art Deco look of the 2006 Cybermen design follows that from the web cast "Real Time". According to the episode commentary, Graeme Harper wanted an Art Deco feel to the parallel universe Earth. Art Deco costumes had previously been used for the K1 Robot in "Robot" (1974) and for much of the cast (including robots) in "The Robots of Death" (1977). The Art Deco design, as well as the robotic movements of the Cybermen, are reminiscent of Metropolis (1927).
24. This story marked the long-awaited return to the series of Graeme Harper, who was one of the most celebrated directors of the original series for his work on two serials, Doctor Who: The Caves of Androzani: Part One (1984) and Doctor Who: Revelation of the Daleks: Part One (1985). He had been asked to direct Doctor Who: Battlefield: Part One (1989) but proved unavailable and was also scheduled to direct the aborted 30th anniversary special "The Dark Dimension". Harper actually contacted the production team about his desire to work on the new series. He became the only person to direct episodes of the original series and the revival.
25. Mickey's line "everything is the same just a bit different" is similar to a line by Daniel Jackson in Stargate SG-1 (1997).
26. Adam Shaw was cast at a day's notice.
27. This episode takes place on February 1, 2007.
28. The original script for Doctor Who: Tooth and Claw (2006) had Queen Victoria killed by the werewolf in 1879, which would be the point of divergence for the alternate history in which Rise of the Cybermen is set. This was deemed too confusing and unnecessary, so the origin was left undefined.
29. This is the first episode in which the Doctor breaks tradition of wearing white plimsolls with his brown suit, red plimsolls with his blue suit and black plimsolls with his black suit by wearing black ones with his brown suit. This occurs again later in Doctor Who: The Impossible Planet (2006), Doctor Who: Love & Monsters (2006) and Doctor Who: Fear Her (2006) in which he wears the same combination as in this episode.
30. Early reports erroneously gave the title of this story as "Rise of the Cyberman".
31. When Rose's phone picks up the Cybus network and connects, a video plays during which you can hear a man say, "And it's good news for Great Britain as John Lumic returns to the country of his birth. Mr Lumic, the inventor of high contact metal, has denied reports of ill health."
32. The parallel universe of this Doctor Who episode in which zeppelins were now part of everyday life, bears the same conceptual idea of the parallel universe throughout the US based FOX show Fringe, wherein that show's parallel universe, zeppelins were also heavily part of normal life. It is unclear if the use of zeppelins in both shows' parallel universes was intentional.
33. Mickey's alternate world counterpart is named Ricky. This is the name the ninth Doctor (Christopher Eccleston) mistakenly and then repeatedly called Mickey -- although it was ambiguous whether the Doctor did this because he forgot, or simply to irritate Mickey.
34. Unlike the two-part stories from the first season, this episode featured no "Next time" trailer for the next episode - only a title card reading "To be continued...", the first time the phrase has ever been used to end an episode in the programme's history. The production team had stated previously that one episode in this series was so long that there was no time for a preview. Many viewers, and Steven Moffat, had criticised the use of a preview for Doctor Who: World War Three (2005) at the end of Doctor Who: Aliens of London (2005) as it spoiled the dramatic cliffhanger ending. Beginning with Doctor Who: The Impossible Planet (2006), trailers for the second part of stories were run during the middle eight, after the main credits, to allow viewers time to switch off.
35. When the Doctor tried to stop Mickey and Rose from running off, Mickey called himself "the spare part." Which the story was based on the Doctor Who radio drama Spare Parts. Or could be foreshadow for the Cybermen that would appear at the end of the episode.

The Age of Steel

1. The marching of thousands of mind-controlled Londoners to Battersea (referred to by the Doctor as "sheep") echoes the Pink Floyd song "Sheep" from their album Animals, where the sheep are led into the "valley of steel" to be slaughtered. The album also features a shot of Battersea Power Station on its cover, with a pig floating above it just like Lumic's own airship. Pink Floyd is known for incorporating the Doctor Who (1963) theme music into live performances of the song "One of These Days".
2. Roger Lloyd Pack and David Tennant previously appeared as father Barty Crouch and son Barty Crouch Jr (respectably) in Harry Potter and the Goblet of Fire (2005). In that story, Lloyd-Pack was on the side of the heroes and Tennant was a villain.
3. This episode takes place from February 1 to February 2, 2007.
4. According to an interview with Andrew Hayden-Smith, and comments given by Russell T. Davies in a press conference, Ricky and Jake were initially intended to be gay and lovers. A deleted scene included in the Complete Series Two DVD box set confirms this.
5. The Doctor tells his companions that they will attack from three sides; above, between, below. In Doctor Who: The Five Doctors (1983), to gain access to the Dark Tower, The Second Doctor recites the Gallifreyan nursery rhyme; "Who unto Rassilon's Tower would go/Must choose Above, Between, Below!".
6. The average overnight viewing figure for this episode was 6.85 million (a 36% share), peaking at 7.635 million viewers on its original transmission.
7. This episode, along with Doctor Who: Rise of the Cybermen (2006) was produced in the same production block as the series finale story, Doctor Who: Army of Ghosts (2006)/Doctor Who: Doomsday (2006).
8. Lumic's expression of "Excellent!" is a reference to the off-key rendition of the word that the Cybermen have used in previous stories (beginning with Doctor Who: Revenge of the Cybermen: Part One (1975)).
9. The character of the Newsreader was added after filming had finished.
10. As noted by Noel Clarke on the commentary, Mickey phones Rose and says "I'm coming to get you!", which echoes the Ninth Doctor's words to her at the climax of Doctor Who: Bad Wolf (2005). The words also constitute a catchphrase used by Davina McCall on Big Brother (2000), the latest series of which started two days prior to the episode's broadcast and which also featured in "Bad Wolf".
11. This episode and Doctor Who: Rise of the Cybermen (2006) were inspired by the audio story "Spare Parts", which was released in 2002. In that story, which takes place before Doctor Who: The Tenth Planet: Episode 1 (1966), the fifth Doctor (Peter Davison) and Nyssa (Sarah Sutton) land on the planet Mondas, where they discover the origins of the Cybermen. The story's writer Marc Platt received acknowledgment for his idea.
12. Sally was originally named Kerry.
13. Mickey leaves in this episode, choosing to assume the role of his deceased doppelgänger Ricky and continue his fight against the Cybermen, making him the first companion in the new series to leave the TARDIS crew by choice.
14. In the original script, Rose killed the Cyberman Jackie.
15. In the original script, the emotive Cyberman euthanised by The Doctor was an 11-year-old boy.
16. As the Doctor says goodbye to Mickey, he jokingly calls him "Mickey the Idiot". This was a nickname The Ninth Doctor used for him more harshly. The Doctor also refers to this nickname when, during his debate with Lumic, he continuously uses the word "idiot" while trying to drop clues to Mickey.
17. According to an interview with Andrew Hayden-Smith, and comments given by Russell T. Davies in a press conference, Ricky and Jake were initially intended to be gay and lovers. A deleted scene included in the Complete Series Two DVD box set confirms this, but a hint to this storyline remains in Jake's volatile response to news of Ricky's death.
18. In the original ending, the link between the TARDIS and the other universe was just sufficient to allow the Doctor to take "his" Jackie there, to be united with the "other" Pete, while Rose elects to continue travelling with the Doctor. However, Russell T. Davies subsequently felt that this was too depressing a choice to confront Rose at this stage in the season, especially given that the alternative world would be revisited in Doctor Who: Army of Ghosts (2006)/Doctor Who: Doomsday (2006).
19. If you include all of the deaths of the converted civilians then this episode had the highest death count up until this point in the new series, While Doctor Who: The Parting of the Ways (2005) glossed over the supposed bombing of multiple continents by the Daleks, it is left unsure if there were significant mortality figures due to this fact.
20. When Lumic is "upgraded" to Cyber Controller, Roger Lloyd Pack, who plays Lumic in human form, actually provided the controller's voice along with Nicholas Briggs. Listen carefully and you will be able to tell the difference between voices. Lumic's/controller's voice sounds more human in terms of tone.
21. The climax echoes that of Casablanca (1942), with Mickey in the role of Rick Blaine and Rose as Ilsa Lund. Indeed, Mickey adopts the name "Ricky" and talks about freeing Paris.
22. Several elements of this story refer back to the 1967 Doctor Who (1963) story "The Tomb of the Cybermen", specifically, the Cybermen using a form of mind control, characters being startled by a mock-up Cyberman, and Cybermen killing with electricity from their hands.
23. The 1968 Doctor Who (1963) serial "The Invasion" also saw the use of emotions to kill Cybermen.
24. During the spontaneously explosive climax, the shots of the explosions are a reuse of the similarly explosive climax of Doctor Who: Rose (2005), specifically the moment the Nestene Consciousness is destroyed by 'anti-plastic'.
25. The climactic action involving the destruction of the Cybercontroller took place in a lift rather than on the roof, with the transformed Lumic trying to break through the compartment's floor.
26. Upon learning about the emotional inhibitors, the Doctor says to Mrs. Moore, "Do I have that right?" This echoes the same line said by The Fourth Doctor when he is faced with the prospect of destroying the Daleks in Doctor Who: Genesis of the Daleks: Part Six (1975).
27. Mrs. Moore originally died in the cooling tunnels.

The Idiot's Lantern

1. In the script there are a lot of references to the strange activity happening around Florizel Street. Florizel Street was the original name for Coronation Street (1960).
2. The line spoken by The Wire: "Are you sitting comfortably? Then I'll begin" was the opening for the BBC radio program "Listen with Mother", which ran from 1950 until 1982.
3. Torchwood Reference: Although you can barely hear it, Detective Inspector Bishop says to his colleague that "Torchwood will be all over us", behind The Doctor after Rose is brought in to the office.
4. Originally, the Doctor was supposed to have a line about having trouble with radio transmitters, which was supposed to be a reference to Doctor Who: Logopolis: Part Four (1981), where the Fourth Doctor fell from the Pharos Project transmitter to his death.
5. Almost every scene is filmed at a Dutch angle.
6. The Doctor makes a reference to the song "Never Too Late" by Kylie Minogue, who later starred in Doctor Who: Voyage of the Damned (2007).
7. Includes the scenes from the actual coronation ceremony of Queen Elizabeth II in 1953.
8. During stock footage showing the coronation of Queen Elizabeth II, the narrator can be heard saying that the Queen's dress was designed by Norman Hartnell. This was the second cousin of William Hartnell, the original Doctor Who (1963).
9. All the television aerials seem to resemble Nazi swastikas. On the DVD commentary, one of the set designers mentions that this was done to evoke the post-war era.
10. Mark Gatiss originally wrote the script with the Ninth Doctor in mind.
11. Maureen Lipman shot her role in half a day at Alexandra Place.
12. Nicholas Hoult auditioned for Tommy Connelly, but was deemed too young for the role.
13. Margaret John (Grandma Connelly), also played Megan Jones in Doctor Who: Fury from the Deep: Episode 4 (1968)/Doctor Who: Fury from the Deep: Episode 5 (1968)/Doctor Who: Fury from the Deep: Episode 6 (1968). She thereby held the record for greatest span of time between guest appearances.
14. The Wire's repeated demand, "Feed me!", is reminiscent of a similar demand made, to comic effect, by the killer plant Audrey Junior/Audrey II in The Little Shop of Horrors (1960)/Little Shop of Horrors (1986). When the faces are shown on the screens in the TVs, it is also similar in the original film when Audrey Junior finally bloomed showing the faces of all its victims.
15. The chase scene was originally much longer and included action in the London Underground.
16. This was originally to have been the ninth episode of Series 2.
17. Mark Gatiss wanted to include references to The Quatermass Experiment (1953), but ultimately only the clenching hands of the faceless victims survived.
18. This story had working titles of: 'Mr Sandman', 'Sonic Doom' and 'The One-Eyed Monster'.
19. According to Mark Gatiss, Tommy was gay in the original script and fancied the Doctor.
20. The title "The Idiot's Lantern" was suggested by writer Gareth Roberts, who recalled the term being used by his father to refer to television.
21. This episode was watched by 6.758 million viewers on its original transmission.
22. Magpie was originally a more malevolent figure. His villainous nature was toned down at Russell T. Davies' suggestion.
23. A subplot in which Rose visits her aunt, who works on a game show for the BBC, was deleted because Russell T. Davies feared that having the Corporation be too involved in the plot would make it difficult to take seriously.
24. The story originally took place on Powell Street, intended to be the same location where Rose Tyler's apartment block, the Powell Estate, would later be built. However, since Rose's home had already been established as being situated in the south of London, this would make setting the climax at Alexandra Palace a more cumbersome plot element.
25. The story was originally set during the dawn of the rock 'n roll era of the late Fifties. However, it was eventually agreed that the idea of a living song did not translate sufficiently well to television.
26. The Doctor gels his hair back 1950s style for this episode.
27. Tommy's grandfather was removed from the script. At one point, he appeared in place of the grandmother.
28. The entrance to Bishop's headquarters was originally concealed by a newspaper vendor rather than a market stall.
29. Lara Phillipart, who plays a little girl at the coronation watch party, later played Jasmine in Torchwood: Small Worlds (2006).
30. This episode takes place on 1 June and 2 June 2 1953.
31. Magpie Electricals apparently continues to exist beyond the death of Mr Magpie; as Magpie products are seen in Doctor Who: The Sound of Drums (2007), Doctor Who: Voyage of the Damned (2007), Doctor Who: The End of Time: Part Two (2010), Doctor Who: The Beast Below (2010), and Doctor Who: The Lie of the Land (2017).
32. Tommy, the one clever person in 1953, wears an outfit that almost perfectly matches The Doctor's - brown jacket, blue shirt and white undershirt. A subtle hint about how important his character is to the plot.
33. The street party in the last scene was intended to be set at night, complete with fireworks. This was altered as it was felt to be too similar to the conclusion of Doctor Who: Fear Her (2006) later in the season.
34. The climax originally featured the television sets in Magpie's shop exploding after the defeat of the Wire.

The Impossible Planet

1. Sound effects matching the door opening and closing sounds from Doom (1993) are occasionally used (especially noticeable when Toby goes searching for the "voices" distracting him from his archaeological findings).
2. The simple name of the Ood was an intentional contrast to Russell T. Davies' typical flair for ostentatious alien monikers.
3. First appearance of the servant-bred species, the Ood.
4. Originally, the Slitheen were going to be in this episode. or, more specifically, another family from the planet Raxacoricofallapatorius - with the idea being that they had become enslaved by humanity. The Raxacoricofallapatorians secretly believed that the planet being explored was actually the dwelling place of their god, who would free them from servitude. However, Russell T. Davies ultimately became concerned that the presence of the returning monsters was detracting from the humans whose pioneer spirit he felt was at the heart of the tale.
5. This is the first episode of the revived series to use a quarry as an alien planet - quarries were frequently used in this manner in the original Doctor Who (1963). Russell T. Davies was not a fan of this production decision.
6. The sanctuary base was inspired by the Nostromo from Alien (1979). Parts of the yellow helmets worn by The Doctor and his team, the sides and rear, NOT the front, looked very similar to parts of the space helmets worn in the same movie.
7. The lines Jefferson recites about 2/3 through ("For how should man die better than facing fearful odds") are from stanza XXVII of the poem "Horatius" by Thomas Babington Macauley. It's a slight misquotation, the actual lines being: "And how can man die better /Than facing fearful odds, / For the ashes of his fathers, / And the temples of his Gods [...]"
8. The planet was originally named Hell.
9. This episode takes place in the 42nd Century.
10. The power of the Gravity field (as calculated by the doctor) says it would take 6^6 every 6 seconds. the number 666 is associated with Satan.
11. The Ood would be later revealed in Doctor Who: Planet of the Ood (2008) to come from a region of space near the Sense Sphere, thus suggesting a genetic relationship between them and the Sensorites. Interestingly, the Sensorites are introduced in Doctor Who: Strangers in Space (1964) in a very similar way to how the Ood are in this episode. Both races at first appear to threaten the Doctor and his companions before they finally reveal their more benign intent.
12. The voice of the Beast is provided by Gabriel Woolf, who also played Sutekh the Destroyer in Doctor Who: Pyramids of Mars: Part Two (1975)/Doctor Who: Pyramids of Mars: Part Three (1975)/Doctor Who: Pyramids of Mars: Part Four (1975). Both the Beast and Sutekh are compared on-screen to Satan.
13. The Ood were inspired by The Sensorites from Doctor Who: Strangers in Space (1964).
14. The only significant edit made in postproduction was a sequence in which the Doctor uses the drillhead to detect the sound of a heartbeat emanating from beneath the planet's surface.
15. The Doctor's line "This'll be the best Christmas Walford has ever had" is a reference to the long-running soap EastEnders (1985), in which Christmas storylines are generally miserable despite characters proclaiming the above hope.
16. Russell T. Davies was inspired by Prince of Darkness (1987) in conceiving a plot about explorers becoming possessed by demonic forces, which he also wanted to serve as a challenge to the Doctor's own belief systems.
17. When talking to the Ood that is serving her food, Rose mentions that she used to be a dinner lady, a reference to Doctor Who: School Reunion (2006).
18. Shaun Parkes, who plays Zachary Cross Flane, previously worked with David Tennant in Casanova (2005), also written by Russell T. Davies. He played Casanova's man servant, Rocco.
19. This episode was watched by 6.316 million viewers on its original transmission.
20. It has been alleged by director James Strong that Danny Webb was last name on the casting ideas list for Jefferson.
21. Gabriel Woolf was cast only after the episode had been written and filmed. Originally, the producers sought out Billie Piper's erstwhile husband Chris Evans to voice the Beast.
22. This is the first episode of the revived series where The Doctor ends up stranded without the TARDIS.
23. The weapons used by Mr Jefferson and his security team are FN P90 series of Personal Defense Weapons.
24. Silas Carson previously played various alien voices in Doctor Who: The End of the World (2005), while Paul Kasey is a veteran at playing various monsters for this series and Torchwood (2006).
25. Billie Piper (Rose) and MyAnna Buring (Scooti) have the same birthday, 22 September.
26. The shots of Scooti's body floating in space were achieved by filming MyAnna Buring floating underwater and painting out the air bubbles.
27. The Ood, while possessed by the Beast, say, "I shall become the manifest," as does the Wire in Doctor Who: The Idiot's Lantern (2006).
28. Scenes of bodies floating in space were filmed on the underwater stage at Pinewood Studios, the first time the series has used this facility, not counting the charity special Comic Relief: Doctor Who - The Curse of Fatal Death (1999).

The Satan Pit

1. Torchwood Reference: When Captain Zachary Cross Flane addresses the Beast, he states that he is "representing the Torchwood archive."
2. The crew only had about 15 minutes left to get the scene where the Doctor gives his big speech to the Devil in the pit done. David Tennant nailed it in one take.
3. The Beast was Russell T. Davies' response to producer Phil Collinson's observation that none of the Doctor's enemies during the first season had been godlike in scale.
4. Due to the shooting schedule (especially the fact that all of the episodes with the Cybermen needed to be shot together), this episode was shot closest to its air date. Combined with the immense amount of CGI work needed in this episode, the production staff was concerned about finishing it by the air date and, in fact, were unable to provide a preview tape to the media as they usually did (prompting speculation that they did not release a preview because of some big plot-based secret).
5. Except for the final scene and footage from other episodes, the Tenth Doctor is not seen in his regular costume at all.
6. Alternate forms for The Beast included an old man, a gigantic eye or a young girl inspired by one of the avatars of the Senior Partners in Angel (1999) or a mutated future human.
7. Russell T. Davies said that in order to inspire the design of the Beast, he sent the visual designers at The Mill images of paintings by Simon Bisley, a comics artist known for muscular grotesqueries.
8. Coincidentally, this episode was shown in the week of 6/6/06. It followed a wave of Devil-related stories in the media.
9. The Ood's communication balls/weapons are practical props when the Ood are holding them, but CGI when they are being used as weapons and shocking people.
10. This episode takes place in the 42nd Century.
11. Jefferson tells Zack he was a "bit slow" getting to the air vent door, echoing Rose's words in Doctor Who: Dalek (2005).
12. When the production team couldn't figure out what would be at the bottom of the pit, they considered using Davros or The Master.
13. The scenes with the Beast and the Doctor were filmed at Clearwell Caves, last seen as the Sycorax ship in Doctor Who: The Christmas Invasion (2005).
14. Russell T. Davies mentioned that one of many unused ideas for a creature in this episode would be used in series three, this turned out to be the Toclafane from Doctor Who: The Sound of Drums (2007)/Doctor Who: Last of the Time Lords (2007) as revealed via Davies comments in Doctor Who Magazine Series Three Companion.
15. This episode was watched by 6.080 million viewers on its original transmission.
16. The Sanctuary Base 6 corridor set was recycled to become the entrance to the set for Totally Doctor Who (2006).
17. The Beast may be inspired partly by Cthulhu from H.P. Lovecraft's 1926 story. The possessed Ood resemble many popular illustrations of Cthulhu.
18. The Doctor's quote "Oh... the stuff of legends." was the last scene filmed with Billie Piper as Rose Tyler as a regular companion.
19. The closing scene in which the Doctor tells Rose that they're "the stuff of legend" was the final scene Billie Piper shot as a regular cast member on the series; her departure episode, Doctor Who: Doomsday (2006), had been filmed months earlier. Both her and David Tennant were having a hard time making it through the scene.
20. The effect of Toby/the Beast floating in space was achieved by having Will Thorp swimming underwater and removing the air bubbles.
21. Oddly, the deaths of the two unnamed security guards are not mentioned or even acknowledged by the others.
22. The final scene is a bit reminiscent of Star Trek V: The Final Frontier (1989), although the thematic conflict is hardly unique to that movie.

Love & Monsters

1. The episode contains references to the season-wide story arcs of the first four series; the Abzorbaloff got his files on the Doctor from the Torchwood Archive (series 2), but the files on Rose have been corrupted by the Bad Wolf Virus (series 1). The newspaper the Abzorbaloff reads contains a reference to Mr. Saxon leading the election (series 3). Finally, the Abzorbaloff is from Clom, one of the missing planets from series 4.
2. Mr. Saxon reference: just before Elton sees the Absorbaloff's true form, he is reading a paper with a headline reading "Saxon leads polls with 64 percent." Albeit subtle, this is the first reference to the series 3 "Mr Saxon" arc keyword; prior to the series 3 debut, a "Vote Saxon" poster would also appear in Torchwood: Captain Jack Harkness (2007).
3. The Abzorbaloff was designed by a young boy named William Grantham. He had won a competition to design a Doctor Who monster run by the BBC children's TV program Blue Peter (1958) in 2005. William's prize was to visit the set of Doctor Who and see his design being brought to life.
4. Bad Wolf Reference: Mr Kennedy gives the LINDA members a picture Rose from Torchwood archives but there isn't any other information because of the "Bad Wolf Virus"
5. The Hoix (the alien seen chasing and being chased by the Doctor and Rose at the beginning of the episode) was improvised out of bits and pieces the designers had lying around because they were originally only supposed to create the Abzorbaloff, the primary monster in the episode. The director's only request was "lots of drool". Additionally, the Hoix was not named until after filming they needed a name for the credits.
6. Torchwood Reference: Mr Kennedy gives the LINDA members information about the Doctor from Torchwood archives.
7. In the scene where Elton is fixing Jackie Tyler's washing machine, there's an item on the shelf next to her which looks to be the pencil scribble ball the Doctor catches in the following episode Doctor Who: Fear Her (2006).
8. The Doctor mentions that the Abzorbaloff's home planet, Clom, is the twin planet of Raxacoricofallapatorious, the planet from which the series one villains the Slitheen originate.
9. Russell T. Davies was inspired by Buffy the Vampire Slayer: The Zeppo (1999) and Star Trek: The Next Generation: Lower Decks (1994).
10. The chase scene in the beginning with The Doctor, Rose and the monster running in and out of different rooms was intended as a reference to Scooby Doo. However, the exact same type of sight gag has been done in many other TV shows, and in movies dating back to the silents.
11. In the original script, Elton had been witness to more events in Doctor Who (1963) history: in this draft, Elton's third birthday party was evacuated because of the "Shoreditch Incident" (Remembrance of the Daleks), his mother was killed by a plastic daffodil (Terror of the Autons), and Elton also witnessed the Loch Ness Monster rising from the Thames (Terror of the Zygons).
12. There are references to Doctor Who: Rose (2005), Doctor Who: Aliens of London (2005), and Doctor Who: The Christmas Invasion (2005), with new footage showing Elton's point of view of those events. However, Christopher Eccleston, who was The Doctor in the first two examples, is never seen. Many starring actors who have left TV shows have been known to request hefty licencing fees for the use of their images in post-departure clip shows.
13. Both David Tennant (The Doctor) and Shirley Henderson (Ursula) appeared in Harry Potter and the Goblet of Fire (2005) as Barty Crouch Jr. and Moaning Myrtle, respectively.
14. It's implied throughout the episode that Elton is considerably younger than Jackie. In reality, the actors are only two years apart.
15. Peter Kay was cast after he had written a lengthy letter of praise to the production office upon the conclusion of the first season.
16. The Stephen King quote Elton gives is from "The Green Mile".
17. The original concept concerned a female fan of the Doctor's who was essentially stalking him. With a surfeit of strong female characters already conceived for the season, however, Davies decided to instead replace the female stalker with a more well-intentioned male named Elton.
18. The working title for this episode was I Love The Doctor. It was created as a comic strip.
19. Peter Kay was originally offered the role of Elton Pope. He felt the "UFO-spotter type" was too similar to his character on Coronation Street (1960) and much preferred playing the "baddie".
20. The Doctor and Rose have less than 10 minutes of screen time in this episode.
21. When Jackie finds out Elton's motives, she tells him she will protect The Doctor and Rose "until the end of my life", showing how she has come to trust and care about The Doctor in comparison to the first season.
22. The creature that Elton sees at the start of the episode is credited as the "Hoix".
23. The very first scene of the episode, when Elton sees the TARDIS near the warehouses, was originally supposed to be shot at the dockside. However, due to a large shipment of steel cables, that location fell through at the last minute.
24. This is Bella Emberg's third appearance in the series. Her first two roles were with the Jon Pertwee incarnation of the Doctor in Doctor Who: Doctor Who and the Silurians: Episode 6 (1970) and Doctor Who: The Time Warrior: Part Four (1974).
25. The Abzorbaloff was supposed to be about seven feet tall.
26. The acronym "LINDA" was previously used on Why Don't You Just Switch Off Your Television Set and Go and Do Something Less Boring Instead? (1973), which featured the "Liverpool Investigation 'N' Detective Agency". Russell T. Davies worked on the series for some years.
27. This episode received an Audience Appreciation Index (AI) of 76. As of January 2020, this is tied with the first two episodes for the lowest AI.
28. This episode was watched by 6.663 million viewers on its original transmission.
29. LINDA were an obvious parody of Whovian fandom. Whilst Osgood was clearly a lovingly crafted tribute to the fandom, many felt that LINDA was full of "cheapshot" borderline insults to the fandom, so a number choose to always "forget" about this episode.
30. Director Dan Zeff said of the tone the production team wished to capture, "Working with an inspirational design team, we wanted to emphasise a melancholy feel, an emptiness in the world around our characters - big urban spaces that once may have been full of life, but now lay abandoned, rusting, decayed. Amidst this, Elton and his fragile group of friends would almost feel cast adrift - increasingly vulnerable as they are led astray by the sinister Victor Kennedy."
31. This episode takes place in 2007.
32. There are conflicting accounts of William Grantham's reception towards the televised presentation of the Abzorbaloff. Producer Phil Collinson attested in the episode's commentary that Grantham was disappointed by the monster's human-sized depiction, having intended it to be the size of a double-decker bus. However, Grantham stated in the documentary Who Peter: Partners in Time - 1963-1989 (2010) that he enjoyed the Abzorbaloff's presentation. Andrew Pixley's notes for the story in DWMSE 14, published in 2006, provided a middle ground by stating that Grantham enjoyed the Abzorbaloff's depiction, but was bemused by its smaller size.
33. Victor Kennedy was based on Ian Levine.
34. Elton has many Tardis-blue elements in his life when he encounters the Doctor. He's wearing a blue jacket, the abandoned warehouse has blue doors, Rose has a blue jacket and is holding blue bucket, and there's a blue cabinet visible in frame of his first video log.
35. During the chorus of the Electric Light Orchestra song "Don't Bring Me Down", the members of the band sing the word "Groos"... a made-up word.
36. Bizarrely, due to the way it treats the fanbase stereotypes and its overall vibe as a Dr Who episode, some broadcasters skip this episode completely, when re-running the season, and don't show it in a later slot. Partly as it brings nothing to the story arcs, and it feels like a weird Peter Kay "vanity project".
37. This is the only episode where Jackie has more screen time than The Doctor and/or Rose.
38. This episode was deliberately written to feature only a small amount of The Doctor and Rose, so the Doctorless and Roseless bulk of the episode could be shot at the same time as those two were filming Doctor Who: The Impossible Planet (2006)/Doctor Who: The Satan Pit (2006) (called being "double backed".) Similar "Doctor lite" and "Companion lite" episodes have been used in almost every season since.
39. The Hoix proved so popular that it would later be reused in Torchwood: Exit Wounds (2008) as one of the Alien Incursions caused by the Torchwood Team opening 'The Rift.' It was also featured in the Torchwood Action Figure line
40. Peter Kay cited this episode as the biggest regret of his career. He recalled - "I loved making it but when I saw it, I thought, 'Oh my God. I'm big green lizard running around Cardiff? Is that it?'"

Fear Her

1. This story idea of the Tenth Doctor's involvement in the 2012 Olympics sparked a petition from thousands of fans all over the world wishing David Tennant to carry the Olympic Torch. However, it was not Tennant, but his successor Matt Smith who would carry the 2012 Olympic torch in Wales on 26 May 2012.
2. This episode takes place in summer but was actually filmed in January. Concerns over the fact that the actors' breath was sometimes visible (most notably in the scene where the neighbors are yelling at each other in the middle of the street) prompted the inclusion of the Doctor's line at the beginning referencing the cold and wondering if someone was sucking the heat out.
3. While they haven't dismissed the episode as being outright bad, David Tennant, Russell T. Davies and Euros Lyn have all gone on record as admitting that the episode could have been a lot better, and was hurt by a lack of budget and rushed writing and filming schedules.
4. This episode replaced a submission called "The 1920s" by Stephen Fry. It was abandoned when Fry was unavailable for rewrites and due to budgetary concerns.
5. Abisola Agbaje had to play both Chloe's normal character and her character while being possessed by the Isolus, which Agbaje felt was "weird". When performing as the Isolus she had to whisper, and an echo was added in post-production. Agbaje found it "a bit hard to whisper" because she had a husky voice.
6. In response to the negative reviews of this episode (it is often regarded as one of the worst of the revived series, if not the worst), Matthew Graham said that the episode was written explicitly with children in mind and not adults.
7. The ball bearing decorations on cakes and cookies that the Doctor love so much and raves about are actually called silver dragees and were originally made with mercury or silver over a candy Center. Now, they are just made with edible, non-toxic colors and sugars. Completely edible
8. Matthew Graham originally pitched a storyline in which the Doctor and Rose are faced with a man who has discovered how to drain things of their beauty, leaving his planet a sterile grey landscape.
9. This episode takes place on 27 July 2012.
10. The London 2012 logo seen at the start is the bid logo, not the final logo of the games, which wasn't unveiled until after the episode was produced.
11. In the real world, it was legendary rower Sir Steve Redgrave who finally delivered the torch to the Olympic Stadium in London, and a group of seven young athletes who lit the Olympic Flame. However, newsreader Huw Edwards did provide the commentary on the ceremony, and during one of the elaborate production numbers prior to this the sound of the TARDIS materialising was also heard. Also, the torch in this episode is at least similar to the actual one.
12. This is not the first time David Tennant and Nina Sosanya have worked together. In 2005 they were both prominently featured in the TV mini-series Casanova (2005), written also by Russell T. Davies, where Tennant played the title role.
13. Working titles for this episode included Chloe Webber Destroys the Earth and You're a Bad Girl, Chloe Webber. Both of these were rejected by Russell T. Davies for being too long.
14. The Isolus was inspired by the villains from Invasion of the Body Snatchers (1978).
15. At one point, the story took place on another planet.
16. This episode was watched by 7.137 million viewers on its original transmission.
17. A hand double for Abisola Agbaje drew the pictures, while the series' storyboarder Shaun Williams drew the father in the cupboard.
18. Matthew Graham noted on the DVD commentary that the scribble creature was never to be called a "scribble monster", as the Doctor would never call anything a monster.
19. The episode was filmed during late January and early February 2006, with the cold temperatures experienced during filming being explained in the plot as part of the Isolus' endothermic nature.
20. Abisola Agbaje was discovered at an after-school drama club, where casting director Andy Pryor had held auditions for the part.
21. Nina Sosanya and Abdul Salis had both appeared in Love Actually (2003).
22. The idea of a child bringing things to life through drawings was also featured in Eerie, Indiana: Who's Who (1991).
23. The Doctor's dislike for cats is a reference to Doctor Who: New Earth (2006).
24. Dame Kelly Holmes was offered a cameo as herself. She was busy with Dancing on Ice (2006)
25. Tim Faraday appeared in another popular time travel centric TV show Primeval (2007) as The Janitor Clone. He often appeared along side himself as part of an army of identical clones used to travel through Time Portals to capture prehistoric creatures
26. Dale Hicks was born on 16 January 2001.
27. The second story in the series where no one dies, following Doctor Who: The Empty Child (2005)/Doctor Who: The Doctor Dances (2005).
28. The scene where the cat walks into the box and then disappears is a reference to Schrodinger's cat. Only that cat is either dead or alive it doesn't disappear. However in the novel, Dirk Gently's Holistic Derective Agency, the experiment is conducted. In that case the cat also disappears.

Army of Ghosts

1. First usage of The Tenth Doctor's catchphrase "Allons-y".
2. When Rose emerges from the Tardis after Torchwood moves it, the Egyptian Sarcophagus it's parked aside, is from Doctor Who: Pyramids of Mars: Part One (1975), where it served as the Osirian Time-Space Tunnel conduit.
3. Murray Gold's theme to Torchwood (2006) debuts in this episode as incidental music.
4. Russell T. Davies had originally intended for Torchwood to be based in Cardiff, on the time rift, as had been introduced in Doctor Who: The Unquiet Dead (2005). However, for this episode's plot structure, Torchwood is based at Canary Wharf, in London, but, when Torchwood (2006) went to series, Davies took the opportunity to base them back in Cardiff, Wales.
5. The working title for this episode was Torchwood Rises.
6. To ensure that Noel Clarke and Shaun Dingwall (Mickey Smith and Pete Tyler, respectively) were available for filming, the story was filmed in the season's third production block along with Doctor Who: Rise of the Cybermen (2006) and Doctor Who: The Age of Steel (2006).
7. David Warwick, who plays the police commissioner, played Kimus in Doctor Who: The Pirate Planet: Part One (1978) and was the partner of Louise Jameson who played the Fourth Doctor's companion Leela.
8. Graeme Harper's penchant for including a distorted image of a main character is present in this story. Though not included in every single story he's directed for BBC Wales, it's seen often enough to be considered something of a directorial "signature". Similar distortion is achieved through the use of other magnifying glasses in Doctor Who: The Unicorn and the Wasp (2008) and Doctor Who: Utopia (2007), a curved window in Doctor Who: Journey's End (2008), and with mirrors in Doctor Who: Turn Left (2008). This time, it's the Doctor that gets "the Harper treatment".
9. The footage of Canary Wharf used when Jackie looks out of the window is taken from The Apprentice UK: Episode #2.1 (2006).
10. Yvonne Hartman was originally written for a older actress but when none of the performers in that age range were free. The much younger Tracy-Ann Oberman was hired.
11. This episode was watched by 8.19 million viewers on its original transmission.
12. In the show-within-a-show scene of EastEnders (1985), the character of Peggy Mitchell is seen throwing the 'ghost' of Den Watts out of the pub. In the series, the character of "Dirty" Den Watts was married to Chrissie Watts, played by Tracy-Ann Oberman, who features prominently in this episode.
13. This episode takes place in 2007.
14. Graeme Harper both acted and directed in the original Doctor Who (1963).
15. Freema Agyeman: as Adeola Oshodi, an employee of the Torchwood Institute. Freema went on to play Martha Jones, the Doctor's companion after Rose Tyler. It was later revealed Martha was Adeola's cousin.
16. In the clip parodying EastEnders (1985), the 'ghost' being shouted at stands directly in front of two bronze objects on the mantle, visible from about ear-height. As the 'ghost' keeps shifting from left-and-right, the distortion around it causes the objects to appear as two thin tubes stretching up and joining over the top of its head; a very subtle clue as to the ghosts' true nature.
17. Russell T. Davies has stated he would've rewritten this episode so Adeola survived had he known Freema Agyeman would turn out to be a perfect casting choice to fill the soon-to-be-vacant companion role.
18. In each series, there are several underlying story arcs which span across all episodes until their meanings are fully explained. In season 2, one story arc involved The Torchwood Institute. In this episode and the following - Doctor Who: Doomsday (2006), the events take place almost exclusively within Torchwood Tower, and the projects of the Institute are explained.
19. The characters Gareth Evans and Adeola Oshodi, while presumed to have died at the end of the episode, have definite parallels with the future Torchwood (2006) couple of Ianto Jones and Lisa Hallett: all four worked for Torchwood London, Gareth had a penchant for suits and bold coloured shirts, both couples were biracial, and they were all caught up in the Cybermen-Dalek attack on Torchwood at Canary Wharf. The character's name Gareth correlated with Ianto Jones's actor Gareth David-Lloyd. Furthermore, flashbacks during Torchwood: Cyberwoman (2006) revealed Ianto dragging Lisa through Torchwood London in a room filled with plastic sheeting that was identical to the room and scene where Adeola was converted by the Cybermen after following Gareth into a cordoned off room.
20. This episode has the Cybermen from Pete's world preparing for invasion by impersonating human dead. Conversely, the Cybermen, who are possibly the Mondas variety, are created in the episode Doctor Who: Dark Water (2014) by the Cybermen uploading the consciousness of dead humans into bodies of Cybermen.
21. The scene in which the Doctor asks the Cyber-Leader about the Void Ship echoes Doctor Who: The Parting of the Ways (2005) when the Doctor asked the Dalek Emperor how it came up with the word Bad Wolf, which also had the Dalek Emperor replying that it had nothing to do with him, much like the Cyber-Leader said in this episode.

Doomsday

1. A particular piece of music written by regular composer, Murray Gold with vocals from Melanie Pappenheim, caused an influx of emails to the BBC requesting a Doctor Who soundtrack on the back of this piece of music alone. The following year, fans' wishes were granted and a soundtrack was released on the strength of the emails inquiring about that one particular piece of music, the title of which is simply known as "Doomsday".
2. This episode aired the same week as the 2006 World Cup. Radio Times did variant covers of a team of Cybermen and a team of Daleks on a football pitch, the lead holding a football.
3. After explaining that he intends to send the Daleks and Cybermen to hell, Rose asks the Doctor if she can help. The Doctor tells her to set the coordinates "all to six." Assuming the standard X, Y and Z axes, this would make the coordinates 6, 6, 6.
4. This episode was watched by 8.22 million viewers on its original transmission.
5. Dalek Jast was originally named Rabe. This was changed because it sounded too much like Ray.
6. This episode takes place in 2007.
7. Nicholas Briggs revealed that he disagreed with the way one of Dalek Sec's opening lines was portrayed. In its original form, Briggs thought it sounded as though Sec was asking something to another Dalek, but then answering his own question. He asked episode director Graeme Harper if they could split it into two lines, have Sec turn to the Gold Dalek and ask answer the question. Nicholas went on to say Graeme agreed, but they had to get special permission to change the script.
8. One expensive sequence removed from the script at the development stage involved the Doctor and Rose ascending to the top of Torchwood Tower in the Jathaa Sun Glider (described as a "space canoe") mentioned in Doctor Who: Army of Ghosts (2006); this was replaced with the much simpler moment of Jake summoning them into the lift.
9. The working title for this episode was Torchwood Falls.
10. Some elements of the story were inspired by Philip Pullman's His Dark Materials trilogy. Pullman was "flattered" by the references in the episode, and compared Russell T. Davies' actions to his own practice of referencing works.
11. Graeme Harper both acted and directed in the original classic Doctor Who (1963).
12. The Daleks reject the Cybermen's offer to form an alliance. If the Cybermen had told the Daleks that they have a common enemy (The Doctor), then it would have convinced the Daleks to form an alliance.
13. Russell T. Davies ruled out the possibility of killing Rose off on the grounds of it being too demoralising.
14. Julie Gardner confirmed that when Rose said "I love you", The Doctor was going to 'say it back'.
15. Graeme Harper was impressed with David Tennant's and Billie Piper's performances when the Doctor and Rose are separated by the closing of the breach. In an interview, Harper said, "You must not forget you've got actors who need to be allowed to perform. They take on board the technicalities of what you want to do, they rehearse the technicalities and then there's a moment when they want you to 'shush', and allow them to perform, and it is the artist's, it's *their* moment."
16. A key point of debate was the climactic moment in which Rose is saved from the Void. Russell T. Davies and Julie Gardner felt that her rescuer should be Pete, since this would emphasise his acceptance of Rose as his surrogate daughter. However, some thought was given to assigning this role to Mickey, a position championed by Phil Collinson and Noel Clarke.
17. Secrecy was very tight surrounding the filming of the two final scenes of the episode. Only David Tennant and Billie Piper were given the script for their farewell scene in advance, with the director receiving his copy soon before filming. According to Tennant, the filming of the Catherine Tate cameo was a rare example of a surprise being kept without getting spoiled; the scene was shot with minimal crew while the rest of the production team were having their wrap party. As such, the Tate scenes were actually shot long after the Doctor and Rose's farewell scene, which was filmed during an earlier production block.
18. The last appearance of Peter Tyler.
19. The notion of the Genesis Ark needing to be activated by a time traveller was devised to give a reason for the Daleks keeping Rose and Mickey alive for so long at the start of Doomsday. Russell T. Davies also thought that this provided silent motivation for why the Daleks would have chosen to appear in 21st-century London, since it was the most likely time and place to find the Doctor or one of his associates. He opted not to make this explicit, however, since it would pile too much grief upon the Doctor in what was already a tragic story, implicating him in the many deaths.
20. First appearance of Donna Noble.
21. When The Doctor confronts the Cult of Skarro he says he was there at the fall of Arcadia. He then says he may one day come to terms with that. He does in-fact do so in the 50th anniversary special Doctor Who: The Day of the Doctor (2013) in which he along with The Eleventh Doctor and War Doctor save Gallifrey from destruction by sealing it another universe.
